Peregrine's excitement over her upcoming nuptials is short-lived, when a woman's body is discovered during flight attendant training.

In this spin-off to the wildly popular Australian mystery series, Phryne Fisher's long-lost niece, Peregrine (Geraldine Hakewill, Wanted), decides to follow in her stylish footsteps as a lady detective for a new era. With the help of the handsome, straitlaced Detective James Steed (Joel Jackson, Peter Allen) and a group of accomplished women, Peregrine investigates murders in 1960s Melbourne.
